If you're afraid of the dark then chances are most things scare you at 2 am, no matter if they're innocent. But for those of us who aren't, even the most normal things can take on a whole new meaning when done under the cover of night. 

In the daytime, the sound of an ice cream truck is welcomed. But at night, now that is a whole different story. Children laughing in the daytime, again, is pretty normal. But at 2 am? No, thank you. 

And we can all agree that when an Amazon driver rings your doorbell at 8 pm, it's a crime against our sanity. 

So if you think you're brave, try being a woman doing just about anything at 2 in the morning.
